Hire Ruby on Rails developers

Hi! I'm Liz 👋🏼 I'm about as full-stack 🥞 as they come. I started as a QA and automation engineer and now I'm a senior full-stack engineer focusing on Rails and React. Early on as a QA I worked on projects from writing SQL scripts to check data, to automation engineering, to React Native applications, and even helping implement Kafka instances and a team transition to Kubernetes. Then I moved on to development, mostly focusing on Rails / React stacks. I also am very comfortable working in Python. Now I've been a full stack developer for a few years, always carrying my QA mindset with me. I love exploring the ins and outs of a problem, and figuring out where I can pick it apart and expose weaknesses. I'm really great at building relationships with stakeholders, establishing trust and cooperation so that we can all move forward with a project in a very pragmatic way. Pairing with coworkers is always very enjoyable for me. I like the collaboration, but I really value the mentorship the most. Teaching juniors git has become a mainstay for me, as well as coaching them to maintain a calm mindset while debugging, encouraging them to move through issues in a systematic way. And of course I always fit in robust testing, showing folks how to create test suites and pipeline automation that will improve their workflow. Let's talk about how I can contribute to your team and stack 🙌🏻

Senior software engineer with over 10 years of experience as a remote freelancer.

As a developer, what sets me apart is a combination of my journey, skills, and passion for creating meaningful solutions. I started my developer journey fueled by curiosity, diving into various programming languages and frameworks until finding my sweet spot in web development with technologies like Ruby on Rails I'm always pushing myself to learn new things, and recently I've been delving into opening up exciting possibilities for intelligent features in applications.

Wazuuup! I’m Emma, a full stack dev living in Berlin, Germany. Coming from a bilingual background, I fell in love with coding languages in 2021 when I visited a coding school for the first time. Ever since I’ve been hooked and started working as a web dev instructor in April 2022 and as a freelance developer in November of the same year. Now, with nearly two years of diverse project experience under my belt, I am looking for opportunities that offer long-term engagement and the chance to deepen my knowledge. My current projects are software solutions for beekeepers and a Telegram bot designed to assist refugees. I code in Ruby on Rails, HTML/SCSS & Stimulus.js, and I currently study React. Nice to meet you virtually! ☀️

I help Products thrive through user-centered design, and the ability to wear multiple hats. Using Ruby on Rails as my foundation, I've built, deployed, and maintained Products that leverage (React, React Native, Electron, and more recently, Hotwire) as a Solo Developer and UX Designer. (Need help migrating some React code to Hotwire? I can help!) With a background in UX design and 10 years of invaluable lessons, I've developed a keen focus on: Shipping features quickly without big designs upfront. Spotting areas of technical debt early. Enhancing and simplifying UI by minimizing its required interactions. Writing tests that focus on what matters. Recent things that i'm proud of: A small frontend input validations library I made called 'stimulus-inline-input-validations' was included in the Hotwire weekly newsletter. My open source contributions to this very site! (RailsDevs) My article (Using Custom Turbo Actions with StimulusJS) was included in the Short Ruby Newsletter

Throughout my engineering career I have been focused on shipping high quality Ruby on Rails web applications for startups, SMBs, and Enterprise clients through deep collaboration with internal and external team members and relevant parties. I have extensive experience with Ruby, Rails, Hotwire/Turbo/Stimulus, JavaScript, React, automated testing, DevOps/Infrastructure, mentorship, and optimizing the developer experience. I am deeply interested in building web applications that deliver high value both from a technical and a business perspective. In addition to complex, well-tested, and high quality RoR development, I have experience implementing CI/CD workflows, DevOps, external integrations, ETL pipelines, and complex feature requests that require robust collaboration with stakeholders. I constantly seek opportunities to mentor engineers and to stretch my own knowledge and expertise.

👋🏻 ㅤI am a Full Stack Developer with 8+ years industry experience building web/mobile applications, also passionate about UX. I specialize in Ruby on Rails and JavaScript Frameworks (React & React Native).

I work as a Fractional CTO, Ruby on Rails Developer, and Data Engineer. As a Fractional CTO, I practice immersive leadership—I engage with every layer of the business. I work alongside developers, directly contributing code to the project. I work with founders to create accurate timelines and accelerate time to market, and with vendors to ensure that the business and technology strategies are aligned. As a Ruby on Rails Developer, I focus on scaling legacy Rails applications and optimizing PostgreSQL databases. I especially enjoy working with modern Rails and developed httpscout.io, a website uptime monitoring service, using Rails 7. As a Data Engineer, I work with Python and the "PyData" stack, particularly focusing on e-commerce time series data. I prefer leveraging existing technology and using open-source solutions wherever possible. My approach is iterative, and I work closely with stakeholders to ensure we build precisely what’s necessary to drive key business objectives. I am always open to engaging in interesting projects.

Moved in Belgium 2 years ago in order to chase my passion of becoming a developer. I'm currently located in Brussels, but am open to relocation, if a good enough opportunity arises. Having already a tech background studying Electrical and Computer Engineering back in Greece, I participated in a 6 month boot-camp in order to gain some expertise. Having worked in a couple of projects during my boot-camp, I feel confident to start with a Junior level position, but I'm very certain that there is a lot to learn. As a matter of fact, I'm looking for all kinds of ways to gain experience. Some key functionalities that I worked on my last project: -Chat GPT API integration for dynamic content creation -Self-hosted instance of Stable Diffusion (to mitigate delays from traffic congestion) for art generation functionalities -Utilization of ActionCable and Sidekiq for asynchronous data exchange and job handling EXPERTISE -HTML -CSS -Boostrap -Javascript, AJAX and Stimulus -Websockets -Sidekiq -SQL and PostgreSQL

Who am I? I am Tom Dallimore, a developer originally from the UK but now living in SEA. I currently work as a freelance Rails & React Developer, my 2 favourite frameworks that I thoroughly enjoy using (so far!). Additionally, in my spare time, I am managing a form builder I launched late last year called JotJab(jotjab.com) and building a subscription/membership application for the Shopify App’s ecosystem. But before we go any further, let’s get to my story and why I think we are a great fit for each other. My story Let’s get started. I am a 34 year old developer who has been developing all kinds of applications and software for the past 16 years. When I started software development (when I was about 16 years old) I learned the basics of HTML, CSS and a little bit of javascript. After that I moved onto PHP and C# for a small time but then stumbled upon Rails. I became intrigued, since when did writing code become so fun and fast? At the time I was working at Dyson as a C# developer, but in the evenings and mornings I was building my own little applications - a lot of fun. I eventually settled on creating an ecommerce app (yeah, I didn’t know at the time how much work that would be), which eventually grew into Trado - an open source e-commerce application. Fast forward a year or so and I was offered a job to work at an agency in Beijing. It was a contract based job which was primarily on upgrading, managing and debugging Rails applications, certainly an interesting experience. From there I decided I wanted to dive back into the world of freelance. I helped several companies launch apps using a mixture of React and Rails, including an online store for PPE supplies, a charity donation web + mobile app and an app for the Shopify Partners ecosystem. Why me? I love to experiment and build tools which help people’s everyday lives be more productive and fun! I would say the most rewarding part of being a developer is seeing apps I helped create become a rewarding tool for the user. I’m not just a developer Over the years I’ve worked on projects with teams and on my own. The latter meant I needed to take up other responsibilities to ensure the delivery of a product. These included tasks such as, server management, UX/Product design, graphic design (my father ran a graphic design agency) and from time to time marketing/branding. Guess you could call it a swiss army knife of skills! Side projects As I previously mentioned, since a young age I’ve always enjoyed tinkering with stuff in my free time. The most recent project is JotJab. At the time I was using Typeform to create forms for communicating with audiences on the web, but I couldn’t stomach their high pricing. So I built an alternative using React, Rails, TailwindCSS and Vite, all hosted on Hetzner and Cloudflare using the amazing Dokku engine (seriously, the best open source PaaS out there!). Staying in touch • I keep updated with the OSS community on Github • I follow a lot on Twitter and actively share daily • I follow a few YouTubers. • And I dabble in Reddit, from time to time. Soft skills I like to talk, throw ideas around, and have long conversations about certain topics. I love to experiment with “outside the box” ideas. I do have opinions, I like to discuss and have a conversation about my opinions, but I also love to change and adapt my opinions based on new information. After hours • I’m always keen to learn new technologies, currently experimenting with Go and Flutter • I have a passion for photography and videographer, mostly when taking trips into the countryside • I do enjoy watching a good series now and again, like Shogun There is a lot more I would like to talk about, but I hope I’ve already convinced you enough to start a conversation. I look forward to hearing from you.
